TYPE-CLEANER FOR TYPE-WRITING MACHINES.

SFECIFICATION forming part of Letters Patent No. 475,777, dated May 31`1892. Application filed December l2, 1891. Serial No. 414,819. (Nomodel.)

To all whom t may concern:

Be it known that I, JOHN R. KEATINGE, a citizen of the United States,and a resident of Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in Type-Cleanersfor Type-Writing Machines, of which the following is a specification.

Myinvention relates to machines for cleaning types mounted on thetype-bars of a typewriting or printing machine; and it consists in animproved apparatus containing a rotary brush mounted upon an uprightshaft having its bearingsin an adjustable frame, as hereinafterdescribed.

In the acccompanying drawings, Figure l is a longitudinal sectionthrough my apparatus placed upon a type-writing machine ready for work.Fig. 2 is a plan view of my apparatus.

Vithin a frame A is mounted in suitable bearings a vertical shaft c,carrying above a crank d and having secured to its lower end a rotarybrush B by means of a split-pin or any other suitable contrivance, whichpermits its easy removal for the purpose of eX- changing the brushes orfor easier transportation and storage. The shaft c, preferably near itslower end, is provided with screwthreads c', which engages with thoseout into the lower bearing a on frame A and with a collar r.

The frame A preferably consists of a eentral portion a, through whichthe shaft c is passing and to which is also secured the lowerscrew-thread bearing a6 by means of Vthe bracket n.5. Two slots 3 neareach end of part a receive pins p, secured upon the extensionpieces aand a2, while the shanks of the thumb-screws t, secured to the extremeends of part u, engage in the slots g, provided thereforin theextension-pieces a and CL2, and thus allow the frame A to be extendedlengthwise, so as to suit the different sizes of typewriting machines.The extension a', which is intended to be placed in front, carries thehandle 7L and below the guide-pieces a4, while to the end of theextension a2 is secured a semi-cylindrical clamp a3.

lVhen the apparatus is designed to be used for one particular size oftype-writing machines only, the handle h, clamp a3, and guidepieces a4will be attached to the respective ends of the part a and the extensionsa and a2, and the thumb-screws and slots will be dispensed withentirely.

The operation of using the apparatus 1s now as follows: The brush B,having b een raised to its highest position, is dropped into the spacebetween type-bars until the frame A touches the two parallel rodsgenerally provided in the front and in the rear 0n the top of atype-writing machine and the extensions d and d2 are set and secured insuch a manner that when the brush is in a central position the clamp a3engages the rod m 1n the rear and the guide-pieces d4 slip over the rodfn in front of the machine. The apparatus having been thus once adjustedcan be used for the same kind of machines by inserting the brush intothe space and then backing the guide-lock as over the bar m and droppingthe guides a4 ,over the bar n and then holding the frame in a centralposition by gently pressing with one hand upon the handle h, While withthe other the shaft c 1s given a number of turns to the right till it ischecked by the collar r, provided upon the shaft c, when the same numberof turns is made to the left, thus returning the brush to its primaryposition. It is evident that the screw provided on the shaft c willcommunicate the reciprocating spiral motion to the outer surface of thebrush and effect a thorough cleaning of the types by bringing freshbristles in contact with the types at each successive turn of the shaft.If the types are arranged in an ellipse instead of in a circle, theoperation has to be repeated twice and the frame should be held in twopositions, the second position of the brush being indicated by dottedlines in Fig. 2 of the drawings.

Having thus described my invention, I claim- In a machine for cleaningthe types of typewriting machines, a frame guided and supported by theparallel guide-rods of the type- Writing machine and provided Withbearings and brackets for a Vertical shaft, in combination with a brushmounted upon a Vertical shaft and capable of receiving a spiralreciprocating motion, as and for the purposes herein shown and setforth.

Signed at New York, in the county of New York and State of New Yorlgthis11th day of December, A. D. 1891.
